Add support for jspm?

[davidblurton]

Seems like a nice way to add support for ES6.

[ ] Replace browserify
[ ] Add jspm bundle to production builds
[ ] Add traceur runtime to production builds

Looks really good 👍

@davidblurton I think we should go for it, except use babel instead of traceur to get bundleSFX to work as expected.

I would like to try out jspm, systemjs and babel.
